How many auxiliary contacts can be added to the LK4QU3N disconnect?

Published date: 04 March 2019

Needs to know the maximum number of contacts they can add.

Product line:
LK disconnect switches, LK4 vario

Auxiliary switches


We have two aux switch options, LK4AD10N which is 1 contact and LK4AD20N which is 2 contacts.  The contacts are field installable as NO or NC, but you can only mount one block onto the LK4QU3N disconnect. 

If additional contacts are needed, consider an interposing relay.
